@Sander : Yes that what i thought at first (before i post this), but renaming all file and class would be tedious work. PHPExcel have many file and each other connected, more worst every file and every class have different name only main class that have same name with file name.

Anyway rightnow i got much simpler solution for extracting data to excel (not "feature full" but its works). Editing/using the view script.
